Permissible or not? Let's learn from each other...

An advice for you brother, there is no “let’s learn from each other…” amongst laymen in complicated matters of the religion, rather we should learn from trusted scholars who bring evidences from Qur’ān and Sunnah As from your comments there are people just giving opinions, “I think this”, “this feels that”. And speaking about Allāhs religion with no knowledge shouldn’t be taken lightly بارك الله فيك

There is nothing wrong with this if it is healthy. Imām Ahmad Ibn Hambal used to write some verses of the Qur'ān and good supplications, wash and drink. Many of tht Salaf used to do it too. This is only modernized as people now use machine to make the writing easy. The ink is usually one that's easily dissolvable. This is fine. Allah knows best.

What some of the Salaf said:

Lol. Nice innovation. May Allah keep us on His straight path. For ruqyah, you blow dry spit three times be it on your palms, the surface of the inflicted area or on the surface of water then you recite the ruqyah. Jazakumllah khairan.

Looks wrong

Wrong

I dont know much, but looks wrong... in fact looks like shirk! May Allah (S.W) guide us all

This is giving some "I need milk then bread" vibes. Stirring it like it is Lipton

One Two Never would have believed it if i did not see these 2 Videos I always Prefer, people post a Link to the Authenticity of the Hadith, so people can learn

@saheh_hadith On Innovation (Bid'ah) The Prophet Muhammad (peace be upon him) said: "Whoever introduces into this matter (i.e., the religion) of ours that which is not from it will have it rejected." (Sahih al-Bukhari and Sahih Muslim)
